Developing effective methods for implementing analytical instrumentation is a significant consideration for designers and manufacturers of contemporary electronic analytical devices. However, effectively performing analysis procedures with electronic devices may create substantial challenges for system designers. For example, increased demands for enhanced device functionality and performance may require more system functionality and require additional resources. An increase in functionality or other requirements may also result in a corresponding detrimental economic impact due to increased production costs and operational inefficiencies.
Furthermore, system capability to perform various enhanced operations may provide additional benefits to a system user, but may also place increased demands on the control and management of various device components. For example, in certain environments, an ion trap device may be utilized to perform various analysis procedures upon ionized test samples. Ions from a test sample trapped within the ion trap may be ejected or “scanned out” in a mass-selective manner through one or more ejection slots in the ion trap, and by detecting the ejected ions, a mass spectrum corresponding to the injected test sample may be created.
The utilization of such ejection slots may cause the electro-magnetic field characteristics of the ion trap to exhibit certain undesired non-linear properties. In order to perform an optimized analysis of ionized test samples, an ion trap should ideally be operated with field characteristics that are as linear as possible. Therefore, in certain embodiments, the physical characteristics of an ion trap may be selected to compensate for the ejection slots, and thereby provide more linear field characteristics within the ion trap.
Altering physical dimensions of an ion trap may improve non-linear field characteristics, but may also result in an unbalanced centerline potential in the ion trap. Such an unbalanced centerline potential may cause various performance problems during operation of the ion trap. For example, ion injection procedures for inserting an ionized test sample into the ion trap may be negatively affected when incoming ions are subject to an unbalanced centerline potential. This unbalanced centerline potential may result in poor injection efficiency or significant mass bias in the trapping efficiency of ion trap devices.
Due to growing demands on system resources and increasing complexity of analysis requirements, it is apparent that developing new techniques for implementing analytical instrumentation is a matter of concern for related electronic technologies. Therefore, for all the foregoing reasons, developing effective techniques for implementing analytical instrumentation remains a significant consideration for designers, manufacturers, and users of contemporary analytical instruments.
